Ok here goes. I started this year with with "just a train under the tree" for my daughter. When I went Ebay crazy and bought a ton of tyco stuff. I went tyco since thats what I had as a kid. Anyway its only 3 weeks after x-mas I have a 4x8 table in my office trackbed all atlas nickel silver track half-laid down. And a Broadway Limited steam engine on the way. Obviously I'm well past the tyco stage and the 9 Locomotives I have from them and probably 25-35 cars shouldent all go to waste. Are the tyco couplers compatible with any of "the good stuff" the modern companies are using now? And does HO scale offer magnetic release couplers like my old lionels did? And how does that work? Sorry for the winded post, but I am a newbie with ALOT of questions. Now who wants to buy some nice tyco sets?
